Summary:
This is a conceptual design project. Awards will be given based on individual feature design ideas, not complete enclosure design although CAD designs will be accepted if that’s the best way you brainstorm. The project submissions won’t necessarily be graded on looks, but functionality. If the design idea is superior, that’s what counts.

Project Objectives:
1) IP 68 fully-waterproof enclosure: (a) PCB uses waterproof USB micro-b connector (b) over molded perimeter gasket.
2) Dust cover for USB micro-b connector: (a) IP6X (only needs to protect from dust/dirt ingression) (b) Reliably stays sealed (c) Not too fragile as to tear/break off.
3) Easy press-fit assembly (matell bosses: Round into Hex Interference fit) (a) 2-6 press fit connectors so that the enclosure can stay sealed, but not too much space is consumed by the connector features. (b) Smallest “Round into Hex Interference fit” connector design possible which is manufacturable.
4) Removable clip feature: (a) accepts clips which clip the enclosure to the underside brim of a hard-hat, and (b) (bonus) accepts a second platform which adheres to the bottom-side of a hard-hat. (c) Clips must be easily exchangeable, durable, and not add too much bulk to the enclosure design. (d) (hint): there aren’t much electronics to the right and left side of the battery allowing for space for these removable clip features.
5) Speaker protective over-Grille: (a) Our previous design just has a hole for the piezo speaker sound output. A waterproof gore vent goes over this hole to allow sound out, but no water in. Design a grill to go over this gore vent hole to protect it from being punctured. (b) This speaker-grille will probably have to be a separately molded piece which snap-fits or glues to the case exterior.
6) Protective over molding for added durability and grip to hard-hat.
7) (optional) Forward-facing window to allow for an integrated flash-light.
8) Contains example electronics: (a) PCB secured internally with clips (press-fit connectors can’t secure the PCB as the PCB would be impinged if the case was crushed) (b) Electronics CAN be slightly re-positioned to accommodate optimal placement of press-fit connectors.

With the rise of Digital and AI into construction industry, the concept of design are tend to be approach to “clean” futuristic look.
Few element of this trend are: 1. White
2. Simple in shape
3. Curvature
In fact, these element not only beautiful, also cost effective in manufacturing the product.
Kindly Look into the PDF file for more details

Clip is provided with overmolded rubber teeth. The groove (where clip attaches with main PCB) will not be full round as molding will be difficult and costly. There are few questions - i m not very convinced with the description that round into rectangular connector should be used. PCB connectors are available and widely used in super tight PCBs. PCB case has snap fitment similar to cellphone cover with overmolded rim.

Hi Everyone, this is a friendly reminder that the project will be closing in less than 7 days. Please submit design examples soon so I can provide feedback for improvement. How is the project going for everyone? Is there any questions?

Similar Contests on Cad Crowd

Submit 10 OnShape assembly files (each pair of glasses must have a unique front part but should have the same arms)
Each one should be a different style (See attached photos for styes.)
(1)Aviator
(1)Cat eye
(2)Oval
(2)Round
(2)Square
(1)Kids
(1)Other - be creative!
Submit 5 renderings of each pair with clear and dark lenses (10 renderings total) with the following views:
*Head-on
*45 degrees
*side view
*overhead
*ISO)
*******IMPORTANT*******
This design must be easy to modify. The workflow and feature organization of the parts is as important as the final shape.
The following two measurements should be driven by a single variable in OnShape:
https://cad.onshape.com/help/Content/variable.htm
*the width of the glasses
*the bridge of the glasses
These two dimensions should DRIVE the width of the frames. When the width of the frame changes its shape should scale uniformly to accommodate the change.
See the attached picture for a better explanation. You can submit your glasses with dimensions anywhere in between the max and min. Just make sure the glasses still look good at the max and min sizes. (Scale all dimensions down by 20% for kids glasses)
Arms and Hinges
**please keep these designs the same for all of the glasses.
The straight part of the arm should also be driven by a variable. Keep the curved part by the ear the same. "picture" example: ___/ will be lengthened to look like _____/
The hinge design should be based on the attached picture. However, there should be countersinks on the top and bottom of the hole to accommodate this screw with a 6mm shaft length.

Please use the "hole feature" when designing the hole and countersinks so they can be modified later if needed. These do not need to be driven by a variable.
Lastly, these will be plastic hinges, the nose pads should be part of the plastic frame and do not need to be easy to edit. (see picture)
Please feel free to reach out with any questions.

IN search of several unique face shields (NOT face mask) designs. Not necessarily for essential workers but rather for everyday use to go to the movies, out to eat or to a concert. Basically, something that people can be ok with wearing in public.
We are not looking for a simple face shield design that you can currently find on Amazon, Ebay or Etsy.
We are LOOKING FOR DESIGN CONCEPT AND DIGITAL SKETCH that is of your creation
To help provide some insight, attached are the submissions which we received but weren't quite good enough. You may use those to come up with alternative design inspirations. Preferably something more fashionable.
Again, please don't ask us for a concept. That is up to you. Should you feel comfortable with this project, please apply below.
We are looking to start ASAP with the right candidate

We have designed a 2.4 GHz transponder that is used for sports timing. We require a plastic housing to be designed for this small wearable device.
The PCB has a solar cell on one side and a small 40 mAh LiPo battery on the other.
The transponder is used in running, cycling and Triathlon type events, so we need it to be completely waterproof, we prefer that the unit is ultrasonically welded to form a hermetically sealed product.
The transponder will need to worn by runners, attached to bicycle forks, attached onto ankle straps, etc. An approach we would like to take with the design is to allow for the transponder itself to have a minimalistic design with a universal mounting option that allows for it to be attached to a separately designed Bike mount, or wrist strap.
Ie: the Bike Mount would be a separate design that cable ties (zip ties) to the front fork of a bicycle, then the transponder clips onto or locks into the bike mount. This would allow for future designed mounting accessories, while keeping the transponder design standard.
The design considerations include:
- The housing must be completely waterproof (Hermetically sealed). We would prefer that the unit is sealed with ultrasonic welding.
- We use a solar cell on the top of the PCB to charge the small LiPo battery, so there should be a transparent section in the housing to allow for light to reach the solar cell so that the LiPo remains charged.
I have attached an image of the transponder as well as an STL file of the PCB Assembly. We can send further information and output files as required.

Hi Everyone!
We are excited to see what the community comes up with! Thank you for your amazing designs. Please let me know if you have any questions.
Overview:
In essence, it's a bracelet that holds multiple days worth of a medication and has some of our custom hardware in it. (hardware is roughly .5" by .75", but will become smaller in the future). Please see sketches for further information
Design:
We would like to be able to store different types of pills in different parts of the bracelet. I've included some very rough concepts of my own, but I am by no means a designer or artist and need help figuring out the best way to do this. The CAD image is something that I quickly made for a first prototype a while ago. It is inefficient in terms of storage and very clunky - not what we are going for. An innovative design is the primary thing that we are looking for. We aren't particularly concerned at this point in time if it has fancy waves on the outside, crystals, or beveled edges. It is still important for the bracelet to be aesthetic, but the "jewelry" aspect of this can be done at a later time. It is far more important that we maximize the number of pills that it can hold without having a massive and uncomfortable bracelet. Furthermore, one concept that we are considering is to have a core bracelet that has our hardware in it and then supplementary 'bands' of the medication. We are open to other design options if you think you have something more optimal! If you only have one medication, then there either would only be one band or there can be place holder pieces/blanks that would go in the places if you were to have multiple medications.
Mechanisms:
Access to the pill should be fairly user friendly. I've thought about many different designs, all ranging from individual compartments with covers, one large cover that snaps over, a sliding cover, and even a spring loaded mechanism that pushes out the pills one at a time. I understand that it will be a bit more difficult to make this bracelet compact. Ideally it would hold 1 weeks worth of medication. With that being said, it would be even better if the bracelet held multiple medications, but that is more pills.
Pills:
The type of pill is something that we're currently working with. The larger pills are about 22mm in the greatest dimension. Most pills are circular or oval shaped. The median is approximately 15 mm. Things like birth control, heart medication, seizure medication, etc.
